The State of Stablecoins
Stablecoins are not just dollar tokens. They are becoming a layer of the financial system - a structural buyer of US debt, a payments rail, and a dollarization force. This report tracks the wider landscape and the macro impact, sourced and dated.
Informational research, not financial advice. Figures are one measure among several, always sourced and dated.
Stable relative to what
A stablecoin is a token engineered to hold steady value against some reference. The reference is usually the US dollar but not always. The chart below shows the relative scale of all six categories. Dollar-pegged coins dominate, but the taxonomy runs wider than the common case this dashboard tracks.
Relative scale of the six value-referenced-token categories, mid-2026. Figures are ranges where aggregators disagree (see methodology). The other five categories combined are roughly 15-16% of the total shown here; RWA/tokenized funds is the largest of the five.

From crypto plumbing to financial infrastructure
Total stablecoin market cap is approximately $300-320B as of mid-2026 (aggregators disagree: CoinMarketCap ~$300B, CoinGecko ~$291B, DefiLlama ~$289B - the range is the honest answer, not a number to pick). USDT and USDC alone control over 80% of supply. Every credible forecaster expects multi-trillion scale by 2030; the disagreement is how fast, not whether.

A quiet buyer of government debt
Stablecoin issuers now hold well over $150B in US Treasuries, mostly short-dated T-bills. Tether's reported ~$141B (Q1 2026 attestation) exceeds the holdings of Germany ($91.3B) and Norway ($104.4B) per the US Treasury TIC Jan 2023 table; combined issuers' ~$182B exceeds Norway. The comparison is duration-mismatched: issuers hold short-dated bills, while TIC ranks total foreign holdings.
Largest holders of US Treasury securities, USD billions. Sovereign nations per US Treasury TIC (Jan 2023, latest published); stablecoin issuers per their own reserve attestations (Tether Q1 2026, combined 4 issuers ~$182B). The comparison is duration-mismatched - issuers hold short-dated T-bills, TIC ranks total (long+short) holdings.
The GENIUS Act (signed July 17-18, 2025) requires payment-stablecoin reserves to be 1:1 in cash, T-bills, or overnight repo, with maturities at 90 days or less. This legally binds issuer demand to the very short end of the yield curve, making issuers permanent, rule-bound T-bill buyers. The effective date is the earlier of 18 months after enactment or 120 days after final rules - estimated November 2026. Rulemaking status changes monthly; re-verify before citing.
See the full regulatory comparison in Section 8.
T-bill maturity bands: why issuers stay short
Reserve composition by maturity, from issuer attestations. Short-term bills (under 90 days) dominate because redemptions can arrive any day; long-dated holdings would force a fire sale.
Sources: Tether Q1 2026 attestation; Circle Q1 2026 reserve report. Yadav and Malone (JIEL 2025) flag the interdependence: mass redemptions of stablecoins could strain short-term Treasury liquidity.
Does this take money out of banks
When a household moves a deposit into a stablecoin, the bank loses cheap funding that funds mortgages and business loans. The research is genuinely contested, not settled. The diagram below shows the mechanism; the callouts below it give both sides, cited and neutral.
A $1 deposit moved to a stablecoin issuer does not disappear - it becomes a Treasury holding instead of bank lending capital. Distribution matters, not just aggregate liquidity.
Banks exposed to stablecoin flows lend less
NY Fed, Staff Report 1185 (Feb 2026)
First direct evidence of liquidity-driven disintermediation. Partner banks run "narrow" to absorb the volatility of stablecoin flows; their loan-to-asset ratios contract versus peers. The ECB (Schnabel, Jun 2026) draws the parallel to 1970s money-market funds draining retail deposits.
Minimal lending impact modeled
White House CEA (Apr 2026)
Assumes a small baseline market. Criticized by Americans for Financial Reform ("a model built to mislead," May 2026) and the Consumer Bankers Association (Apr 2026) for treating recirculated funds as equivalent to retail deposits when they return as concentrated, wholesale, rate-sensitive liabilities that do not support relationship lending.
Both sides are politically situated. The honest answer right now: early evidence, no consensus number.
The yield debate
Should stablecoins pay interest? The GENIUS Act says no for payment stablecoins; the research on yield-bearing variants is contested.

Cheaper, faster money across borders
Cross-border cost is not one number. It is three hops (on-ramp, on-chain, off-ramp) plus the value of time in transit. The calculator below is a StableSense teaching model: every lever is visible, and the scenario table underneath says what we are allowed to claim and from where. It is not a quote, and it is not the World Bank series.
Cost of moving $200 across borders, the World Bank Remittance Prices Worldwide measurement point. Traditional: global average ~6.2% all-in (fee + FX margin, 1-5 days). Stablecoin gas-only: ~$0.10 network fee (seconds). The gas-only figure is the middle hop; a full fiat-to-token-to-fiat journey adds on-ramp and off-ramp FX (see the BPI 0.3-9% range in the scenario table). Race bar width is proportional to all-in cost at $200.

Where adoption is real
Not pilot programs - real, non-trivial volume.

Dollarization from below
When a country's citizens choose the dollar over the national currency at scale, monetary policy loses its transmission mechanism. Stablecoins have turned dollarization from a government-level decision into a tap on a phone. BIS Working Paper 1370 (Jul 2026) found stablecoin flows show little response to capital controls, unlike bank deposits.
Stablecoin purchases as a share of GDP. Turkey is the only country with a measured figure (~4.3%, Chainalysis). Argentina, Nigeria, Lebanon, and Venezuela have strong qualitative and survey evidence but no single comparable GDP-share figure; ranked below Turkey on documented adoption.
Three depegs, three failure modes
A depeg happens when redemption confidence drops. Start with what was supposed to hold the peg, what broke first, and whether the mechanism could recover - not with three price charts alone. Cross-linked with the dashboard Anatomy of a real depeg lesson and the in-app Research tab.
One rulebook, many flavors
By August 2026, every major financial hub has a live stablecoin framework. They converge on full reserve backing, licensed issuers, and the effective death of algorithmic designs. The real divergence is whether foreign dollar stablecoins are welcomed (Singapore) or contained to protect local currencies (EU, UK, Japan). Filter by jurisdiction below.
| Jurisdiction | Framework | Status | Permitted pegs | Algorithmic | Key rules |
|---|
Regulatory status is the most stale-fast category in this report. MiCA enforcement dates, GENIUS rulemaking, UK Oct 2027 go-live, Hong Kong license counts all change monthly. Always timestamp.

A rounding error, with momentum
After eight sections of "this is a big deal," a deliberately humbling close. Today's tokenization is a rounding error against traditional finance. The growth rate is the story, not the current size.
Log scale, USD billions. US money-market funds ~$7.9T (ICI); US gold ETFs ~$530B (World Gold Council); fiat stablecoins ~$316B; RWA ex-stablecoins ~$20-40B (rwa.xyz); tokenized gold ~$5-8B. The ratios are structurally stable for now; the absolute sizes are fast-stale.
Until on-chain real assets approach even 1% of their traditional counterparts, claims that they are "changing" commodity or credit markets should be read as trajectory statements, not current-fact statements. The growth rates, not the sizes, are the story worth monitoring on the live dashboard.
